Rivers are significant geomorphological agent, which shows diversity of form and behavior and quickly respond to disturbances acting against their system. The Bagmati River of the Kathmandu Valley originates from eastern hill Nagarkot in Sudal is the 7th order drainage and stretches about 51 km and flows over the Valley covering 678 km2 of watershed. This river have been suffering from unmanaged urbanization and industrialization, growing population pressure on catchment of river causes destruction of natural phenomenon of river. In addition to such anthropogenic activities, gradual change in several natural phenomena in response to global climate change, such as changing monsoon pattern with changing intensity and amount of precipitation, fluctuation of groundwater table, reduction in discharge of natural springs etc. are influencing the river’s natural processes and dynamism. The present study assesses the morphology of the past and present river courses and identifies effects of climatic factors on the river.
